To translate statements into expressions and equations:

Identify ___________ _____________ that indicate the operation.

Write the numbers/variables in the correct order.
The SUM of
_____________ and _____________ : ______________________
The DIFFERENCE of
_____________ and _____________ : ______________________
The PRODUCT of
_____________ and _____________ : ______________________
The QUOTIENT of
_____________ and _____________ : ______________________
Write each verbal phrase as an algebraic expression.
